本文介绍了在使用GDB调试程序时如何正确处理CTRL+C操作，以实现程序正常中断并获取堆栈跟踪信息。文中提供了两种方法：一是通过输入'signal SIGINT'指令发送信号给被调试程序；二是配置GDB使SIGINT信号直接传递给被调试进程。

My program is determined to stop its execution by hitting CTRL+C in command window. By now, i have a critical error right in this stopping phase, so i want to debug with gdb.

Problem is, gdb redefines CTRL+C as its own interrupt and pauses the execution whet hitted. How can i handle it that CTRL+C powers my programm off and gdb can catch the stack trace?

rom the (gdb) prompt, type signal SIGINT. This will send (surprize) SIGINT to the program being debugged.

Alternatively, handle SIGINT nostop print pass will make GDB pass the signal straight to the inferior (being debugged) process.
